What is the significance of God's call in salvation?

God’s call in salvation is twofold: the general call, which goes out to all, and the effectual call, which successfully brings the elect to faith. The effectiveness of this call is emphasized in the analogy of Noah's call to enter the ark; when God commanded 'Come thou,' it was not merely an invitation but a definitive call that Noah obeyed. This reflects how God's call in salvation goes beyond a simple appeal. It transforms the unwilling hearts of sinners, enabling them to respond to the gospel. Thus, believers see their salvation as dependent upon God's sovereign grace and power rather than their own decision-making.
